How are the causes and solutions to error handling related to notify activity

[tr v c]

Hi all,

Currently I am using notify activity to configure the process to run single thread. I have fully configured for notify activity but sometimes when running the process on tea server, the process error is as follows:

process [citadletter_send_response_to_cm.Process] instance faulted, JobId [bw0a102bmjq], ProcessInstanceId [bw0a102bmjq], ParentProcessInstanceId [-], Module [CitadOut_Letter_Send_Response_To_CM:1.0.0.20210219123408], Application [CitadOut_Letter_Send_Response_To_CM.application:1.0].

TIBCO-BW-CORE-500064: Activity [Notify] error.

On the appnode outside the process CitadOut_Letter_Send_Response_To_CM, there are 2 more processes. Does sharing processes using notify activity in the same appnode have any effect Please tell me the cause and how to fix it. I am using Tibco Bussiness Work 6. Thank you.
